Title:
HEAT SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2015148384
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat supply device capable of performing heat recovery and heat supply with respect to bath water by using a common heat exchanger.SOLUTION: A heat supply device includes: a tank for storing a heating medium; a heat source for heating the heating medium in the tank; a heat storage circulation path for circulating the heating medium between the tank and the heat source; a bath water heat exchanger located on the further downstream than the heat source in the heat storage circulation path, and exchanging heat between the heating medium in the tank and the bath water in the bathtub; a bath water circulation path for circulating the bath water between the bath water heat exchanger and the bathtub; and a control device which can selectively execute a heat recovery operation for recovering heat of the bath water and a heat supply operation for supplying heat to the bath water. In the heat recovery operation, circulation of the heating medium by the heat storage circulation path and circulation of the bath water by the bath water circulation path are executed while the heat source is being stopped. In the heat supply operation, circulation of the heating medium by the heat storage circulation path and circulation of the bath water by the bath water circulation path are executed while the heat source is operating.
